Area of Science:

  • Psychology

  • The
  • scar hypothesis
  • proposes that major depression episodes may lead to persistent personality alterations.

Purpose of the Study:

  • To investigate the
  • scar hypothesis
  • by examining personality changes after a first major depressive episode.

Main Methods:

  • Subjects with a prospectively observed first episode of major depression were compared to those who remained well.
  • All participants were mentally healthy at both assessment points.

Main Results:

  • No evidence of negative personality change was found after a first major depression episode.
  • A potential association emerged between the number/duration of episodes and increased emotional reliance/introversion.

Conclusions:

  • Self-reported personality traits appear stable following a typical episode of major depression.
  • Further research is needed to explore personality changes after severe, chronic, or recurrent depression.
